The parts 'of the rotary printing press which have been illustrated herein to give a clear understanding ofthe several parts of my invention comprise a framing 1 on which is supported a feeding table 2. The printing mechanism comprises a first form printing cylinder 3, its impression cylinder 4, a second form rinting cylinder 5 and its impression and a stationary cam 11 being shown in the.

cylin er 6. 'l'he shafts 7 and 8 of the printing and impression cylinders 3 and 4 are mounted in suitable bearings in the framing 1, in position to receive sheets directly from the feeding table. rlhe first impression cylinder 4 of the printing mechanism is provided with a set of grip ers 9 arranged to receive the sheets from t e cutting mechanism as will hereinafter appear. 'lhese grippers 9 are opened and closed at the required moments in the revolution of the cylinder, a spring 10 being shown in dotted lines in Fig. 11 for normally holding the grippers closed same figure for opening the grippers at the requiren time to receive the sheets from the cutting mechanism. Y

rl'he shaft 12 of the second impression cylinder 6 is mounted in the framing 1 of the press in position to bring the periphery of the said cylinder into engagement with theperiphery of the first impression :cylinder 4 and the said second impression cylinder 6 may be provided with sets of grippers 13, 14, arranged to receive the sheets from the first impression cylinder and convey them into position to be rinted' from the second form printing cylin er 5. The shaft 15 of the printing cylinder 5 is suitably mounted in the framing 1 of the press.

The printing mechanism is driven from a drive shaft 16 mounted at 17 in suitable bearings in the framing 1, as follows. A spur gear 18 on the drive shaft 16 meshes with an intermediate gear 1'9 which in turn meshes with a gear 20 on the shaft 15 of the second form printing cylinder 5. This gear 20 in turn meshes with a spur gear 21 on the shaft 12 of the second impression cylinder 6.

les

This ear 21 meshes wit a gear 22 on the shaft 8 of the first impression cylinder 4,

which gear 22 in turn meshes with a gear 23 on the shaft 7 of the first form printing cylinder 3.

In the form shown in Fi s. 1 to 12 inclusive, the blades 24, 25, of t e pair of rotary cutters are arranged to coactv with each other every complete revolution and are drivenl at the same speed as the surface speed of the printing cylinders, the carrier 26 for the blade 24 having gears 27, 28, which mesh with gears 29, 30 fixed tothe carrier 31 of the cutter blade 25. The gear 28 of the carrier 26 is driven from a gear 32 fixed to the shaft 8 of the first impression cylinder. The axes of the cutter carriers 26, 31 shown herein are arranged out of parallelism with the plane of travel of the web and the cutter blades24, 25, are arranged out of parallelism with the axes of rotation of the cutter carriers 26, 31 and in lines which are spiral or oblique relatively to a line parallel with such axes so-as to produce the required shearing cut on the web as it passes through the cutting mechanism. This arrangement is the well known Cottrell type of cutter such as that shown, described and claimed in United States Letters 'Patent No. 391,949 dated October 30, 1888 entitled paper cutting machine and granted to Calvert B. Cottrell.

Ihe shaft 33 of the cutter carrier 31 is suit.: ably mounted in the framing 1. To shorter lengths of,sheets to be assed t rough the cutting mechanism than as heretofore been possible, I make the cutter carrier 26 of crank form, its shaft sections 34, 35, being in alinement and itsy offset portion 36 at the ends of the crank arms 37, 38, forming a support for the cutter blade. The shaft sections 34, 35, are mounted to rotate in stationary supports 39, 40, carried by the framing 1 of the press. the shaft section 34 and the gear 28 is shown as fixed to the shaft section 35 of the cutter carrier exterior to the framing 1.

The webcarrier is shown herein as af'pin Thev gear 27 is shown as fixed to',

carrier and has its axis arranged in paral el-" carrier, in the present instance by providing i the crank arms 37, 38, `of the cutter carrier with rearwardly extended 'branches 44, 45, having elongated slots 46 and providing .the arms 41,.'42 cf the web carrier with rearwardl extended branches 47, 48, in which stud s afts 49, 50 are mounted to rotate, the said stud shafts being provided with eccentric cams 51 located in the elongated slots 46 of.v

the branches 44, 45, of the cutter carrier.- The stationary supports 39, 4Q have fixed 4the sheet'from the the feeding table ,2.

Vat or wit-hin the path thereto gears 52, 58, concentric with the axis of the web carrier and eccentric to the axis of the cutter carrier, around which gears are' fitted to travel in mesh therewith gears 54,

A55 fixed to the stud shafts 49, 50, carried vby the web carrier. These parts are so related that as the cutters are rotated at the same speed as the surface speed of the printing cylinders, the movement of the web carrier will be retarded during the firsthalf ofthe revolution of the cutters after the preceding sheet has been severed from the web and will be accelerated during the second half of the revolution. This carrier, because of its being mounted eccentrically to the axis of rot ation of the Cutter carrier, will describe a circular path which will be beyond the path of the cutter when passing a set of gripper-s on the impression'cylinder'. It is also desirable that the path of the web carrier shall be of the cutter at the point where the two cutters co-act to sever web.

The type of web carrier shown hereinj is a pin carrier and thepins are denoted by 56 and they are mounted to slide in the offset portion 48 of the pin carrier. The movements of these pins are controlled by a rochshaft 57 which is providedrwith an arm 58 connected to spring-actuated means 59 tending to slide thepins outwardly into engagc- A,ment with the advance edge ofthe web at the time the preceding ,sheet is cut therefrom,

a'nd an arm 6() carrying a roll 61 arranged to be engaged by a stationary cam 62 fixed in the presentinstance to the stationary support 40 of the framing 1.- This cam 62 is so arranged that the pins 56 will beheld in theirv withdrawn position until the sheet is about. to be severed from the web when the pins` will be released and permitted to engage the advance edge of the web.

The web roll is denoted'by 6 4 and it isv mounted in vertically sliding bearings 65, which roll 64 is supported upon two friction drive rolls 66, 67, the web 68 being led from the roll 64'around the roll 67 and' from thence upwardly over an idler roll 69 and a drive roll 70, the shafts 71, 72 of which are mounted in the framing 1 adjacent vto the under side of From the drive roll 70, the web 68 is led downwardly to the cutting mechanism. 'Ihe web 68 is held pressed against theroll 70 by an endless tape carrier 7 3 which passes over the roll 70 and an idler roll 74 and aroundrolls 75, 76 to the front i and rear ofthe roll 70,. thus preventing any tendencyefthe web to slip while being fed to the cutting mechanism.

rIhe means which I have shown for driving the web isA as follows. A cross shaft 77 is mounted in suitable bearings in longitudinally adjustable supports 78, which shaft may have gears of different sizes interchangex/ ably fixed thereto according to the speed with which it is required to drive the web 68. In the accompanying size is shown inl Fig. 1 and a gear 89 o f another size is shown in Figs.4 and 5. These gears are shown as fixed to the shaft 77 by `a removable key 81. The supports 78 for the shaft 77 are shown longitudinally adjustable, in the present instance 4by providing the framing with a longitudinal series of holes 82 and the supports 78 with bolts 88 arranged to lenter the desired holes.

adjusting the shaft 77 longitudinally of the press might be employed. The shaft 77 is adjusted to the required position to permit the gear which is fixed thereto, as for indrawings a gear 79 of one l However,it is to v 'be understood that various `other devices for stance the gear 79, to mesh with a gear 84 l mounted in the framing 1, which gear- 84in gear 85 mounted, in the turn meshes with a framing. This gear 85 lmeshes with a gear 86 fixed to the shaft 87 of the friction drive roll 67 This gear 86 'meshes with an'intermediate gear 88 mountedin the framing I. The said intermediatej gear 88 meshes" with a gear 89 fixed tothe shaft 90 of the friction drive roll 66. This shaft 90 has fixedthereto a bevel gear 91 which meshes with abevel gear 92 carried by a power transmitting shaft 93, which shaft has a bevel gear 94 meshing with a bevel gear 95 carried by the shaft 72 The 'gear connection of the drive roll 70. between the roll 66 and the roll 70de` such. that the roll 70 is driven at ,the same surface speed as the rolls 66 and 67.

The speed of the web 68 is increased and decreased during one revolution of the cut?` 4 ters whereby the web, when. the sheet therefrom,l may be driven at the same speed as the cutters. This is. accomplished by providing. a variable drive between the'shafts 16 and 77. as follows. The shaft 16 isprovided with a crank arm 96 having a pin 97 located in a radially elongated slot 98m a counterw balanced arm' 99 fixed tothe shaft 77. vAs

the pin 97 travels around 'the shaft 77 in slid'- ing engagement with itsv arm 99, the move? ment of the shaft will be accelerated andretarded. The arrangement of the twoshafts is such that the greatest speed is imparted to the web at the time' cut therefrom in thev cutting mechanism. will be seen that this variable drive does not that-the sheet is being is cutrio` interfere inany particular with the interchangeable drive fon-feeding a greater vor vlesser length ofw'eb throughv the cutting mechanisml according to the lengths of sheets which it is desired to cut from the web.

In operation it is to be understood th at .the rot-ary cutters are being driven from the driveshaft 16 at they same surface speed as the printing cylinders.

77 l,will bevdriven from its 'las 'The shaft 77 j is lrotated one complete revolution for every 'iso point of highest speed at a gradually lessening speed during onel half of its revolution and then at a gradually accelerated speed during the other half revolution.

A gear of the required size to feed a precietermincd length of sheet through the cutters during one revolution thereof is fixed tothe shaft T7 and the longitudinally adjustable supports 7S are adjusted to bring the gear which is fixed to the shaft 77 into mesh with the train of gearing leading to the web roll driving mechanism. It will be seen that if the adjustable supports 78 are adjusted into position to bring the shafts 77 and 16 into alinement, a full length sheet will be fed through the cutters for every revolution of the cutters and will travel at the same speed as the cutters.

In the construction shown in F ig. 1, when a gear 79 is used on the shaft 77, a threequarter length sheet is fed through the cut; ters, which sheet is caused to travel at the same surface speed as the cutters at the time of cut. Because of the varlable drlve conf nection between the shafts ,77 and 16, the

s eed of the web from which the succeeding s ect is to be cut is gradually decreased during one half of a revolution of the cutters. This will allow the web carrier to be retarded in its movement during the first half revolution of the cutters. During the next half .revolution of the cutters, the speed of the web is increased and also the speed of the web carrier isaccelerated, thus permitting the web carrier to feed the advance edge of the web into the grippers on the impression cylinder at a greater speed than the surface speed of travel of the impression cylinder, thereby insuring the positive insertion of the advance edge of the web inte the grippers carried by the first impression cylinder. It is also to be seen that because of the eccentricity of the axes of the cutter and web carriers, the ath of the web carrier will bc exterior to tiiepath of the cutter carrierduring the time that the advance edge of the web is being fed into the grippers on the first impression cylinder.

The advancing web and the web carrier are both being driven at the same speed as the cutters at the time of cut but immediately after the cut, the driving mechanism of the web is so timed with respect to the connection between the web carrier and cutter carrier that both the web and the web carrier will be retarded for a part of the revolution of the cutter so as to permit both the speedof the web and the web carrier to be accelerated at the time that the advancingl edge of the web is fed to the printing mechanism. Furthermore, by mounting the axis of the cutter out of parallelism with the plane ofy travel of the advancing web ,and mounting the axis ofthe web carrier 1n`parallelism with the plane of travel of the advancing web, the sheet may be severed alon a line at right angles to the travel of the Weg and the web carrier may be caused to en age the advance edge ofthe web at points a ong a line parallel with the line of cut.

B v making the cutter carrier of crank. shaft ferm a three-quarter or less length of sheet can be readily fed to the first impression cylinder while permitting the cutters to rotate at the same surface speed as the impression cylinders.

In Figs. 3 and 4, I have shown a gear 80 fixed on the shaft 77, which gear is of the required size to permit the Web to be fed to the cutters at a sufficient speed to allow half length sheets to be cut therefrom. This re- 1 sult also can be readily secured because of the crank shaft form of the cutter carrier.

In Figs. 13 to 16 inclusive, another form of rotary cutter is shown in which the cutter is arranged in parallelism with the advancing web and .the offset portion of the cutter is provided with a serrated cuttin blade 24* which is parallel with the axis o the cutter. In Figs. 13 to 15 inclusive, the web carrier is shown as being mounted eccentric to the axis of the cutter, while in Fig. 16 the web carrier is shown as being mounted concentric with the axis of the cutter. In both of these forms the driving connection between the cutter carrier and the web carrier is such that the speed of the web carrier is retarded and accelerated during the constant rotary speed of the cut-ter so as to correspond with t e retardation and acceleration of the advancing web.
